83% of 2025 DeFi hacks were due to access control failures.

Signers carry a lot of responsibility and are constantly targeted by attackers. When they all sit within the same organization, the risk they're exposed to becomes even more concentrated.

Adding independent signers can reduce risk, but only if they have the context and expertise to meaningfully participate. Even experienced signers can become a bottleneck as transaction volume grows. Simply replacing manual review with basic automation isn’t the answer either: automated signing needs clear safeguards and human judgment when something falls outside the expected path.

Aragon adds an independent signing seat to your existing Safe, reducing reliance on signers within a single organization. Our Solidity and security engineers bring the technical context and expertise to meaningfully review critical transactions. For higher-volume workflows, policy-based automation keeps routine transactions moving within defined safeguards, with expert review for exceptions.

How it works

Review your contracts, workflows, and risks

Our Solidity and security engineers review the relevant contracts, transaction flows, privileged roles, and operational dependencies. We work with your team to identify execution risks and where additional controls can strengthen security.

Formalize the signing procedures

We design a signing process around your technical and operational requirements. Depending on the workflow, this can include automated checks, transaction policies, technical review, approval requirements, monitoring, or other purpose-built controls.

Establish a secure signing environment

We operate the signing seat through dedicated infrastructure that isolates signing keys and tightly controls their use. Each component gets only the access it needs, with safeguards around how signatures can be initiated and authorized.

Review and sign

We independently review transactions before signing. Routine workflows can use automated verification and policy checks, while complex or high-risk actions receive technical review from our Solidity and security team.

Coordinate critical responses

We actively monitor the workflows we support and coordinate with other signers and client teams when action is required. Alerts, notifications, escalation channels, and on-call coverage ensure timely responses to urgent proposals, incidents, and emergency actions.

Maintain visibility across execution

Dashboards, logs, and alerts provide a record of signed, rejected, and unresolved transactions. Teams maintain visibility for routine operations, incident response, and auditability.

An institutional approach to signing.

Strengthen security with an independent signer

Reduce reliance on signers within a single organization. Aragon provides an independent signing seat with its own technical review, secure infrastructure, and operational controls.

Scale without creating a signing bottleneck

Keep routine transactions moving as volume grows. We automate checks where appropriate and reserve human review for transactions that require judgment, allowing operations to scale without increasing manual signing with them.

Replace individual signers with an institutional signing function

Business-critical signing shouldn’t depend on individual keyholders. Aragon’s signing function is backed by a team of Solidity and security experts, dedicated infrastructure, and processes designed for operational continuity.

Put expert judgment where it matters

Not every transaction can or should be automated. Aragon’s technical team reviews upgrades, governance actions, exceptions, and other transactions that require deeper context or judgment.

Be ready when action is required

Critical signing responsibilities don’t always happen on schedule. Monitoring, alerts, escalation paths, and coordinated response help ensure the right people are available when urgent or exceptional action is needed.

Under the hood

Secure execution depends on more than a signing key.

Aragon continuously develops the tooling our engineers use to securely review, verify, and execute business-critical onchain transactions. We build purpose-built systems that improve operational security, automation, and visibility across the signing workflow.

EVM Mirror

Before approving critical transactions, it's essential to know the deployed contracts match the code that was audited. EVM Mirror verifies deployed bytecode against verified source code, helping reduce the gap between audit and deployment and giving reviewers greater confidence in what they're authorizing.

Operator tooling

Our signer operations are supported by custom-built tooling for policy evaluation, transaction review, secure execution, and operational monitoring. Live dashboards, automation, and audit trails help our engineers process routine transactions efficiently while maintaining visibility, accountability, and auditability.
